<p>Yolanda Broadcast Scale Bluetooth Device Object</p>
<p>The broadcast scale is a device that does not need to be connected and obtains relevant data through the broadcast sent by the receiving device. The scale is different from the ordinary Bluetooth scale, the difference is that when the ordinary Bluetooth scale scans the surrounding device information, it can initiate a connection to a surrounding device, so you can choose whether to stop scanning the surrounding device information without affecting the connected device To obtain relevant measurement information.</p>
<p>However, because the broadcast scale obtains the broadcast data of the surrounding devices and then analyzes the related measurement information, there is no need to connect a certain device. Therefore, if the scanning of the surrounding equipment is stopped during the measurement process using the broadcast scale, it means that the measurement data of this time cannot be obtained.</p>

<p>When the device supportUnitChange field is true, it indicates that the device is allowed to be modified by agreement, then this method can be used to modify the unit</p>
<p>When the method is successfully called, the SDK will send out a Bluetooth broadcast signal. When the target device&apos;s unit has been modified or 10s, the SDK will stop broadcasting.</p>
<p>After this method is called, the operation of the previously synchronized unit will be canceled, for example, the unit of the A device is being synchronized. When synchronizing the unit of the B device, the SDK will first cancel the synchronization of the A unit and then start the unit synchronization of the B device.</p>
